Dayton's campaign manager confirmed the campaign bought time through the August 10th primary but public records show purchases at most stations only through the end of June. The former senator is spending his own money on the campaign.

Democrat Matt Entenza has bought nearly $850,000 worth of ads at the stations. The former legislator started running ads in late April and bought time through the end of June. Entenza is also using his personal funds on the campaign.

The DFL endorsed candidate for governor, Margaret Anderson Kelliher hasn't bought any ads yet. Her campaign has sent fundraising requests to supporters asking for help to get on the air. Kelliher, Dayton and Entenza are competing for the DFL nomination.
